If the player has unlocked the ability to fish without using bait from the Prawnbroker in the Aquarium of their house, they do not need bait to fish for lava eels. The minimum Constitution level to receive the full amount of healing from this food is 53.

Players who wish to reside in Taverley dungeon for extensive periods of time can bring equipment (logs, tinderbox, oily fishing rod and bait) to fish and cook the lava eels to produce food for combat. This is especially true for players given black demons or blue dragons as a Slayer task.

During the Heroes' Quest, guild-master Achietties will ask players to obtain a cooked lava eel to prove that they are worthy of membership to the Heroes' Guild. Players will then need to visit Gerrant in Port Sarim to learn how to make an oily fishing rod, followed by going to either Taverley Dungeon or the Wilderness Lava Maze to catch an eel.
